Struct FrameStack 

pub struct FrameStack<F> { /* private fields */ }

An explicit activation stack whose depth never consumes the host call stack.

Implementations

impl<F> FrameStack<F>

pub fn new(limit: WorkLimit) -> Self

Creates an empty frame stack using the control organ’s work-limit vocabulary.

pub fn depth(&self) -> usize

Returns the occupied frame depth.

pub fn push(&mut self, frame: F) -> Result<(), FrameStackError>

Admits one frame or returns typed depth exhaustion without recursion.

pub fn pop(&mut self) -> Option<F>

Removes the current frame, if any.

pub fn current(&self) -> Option<&F>

Returns the current frame, if any.

pub fn current_mut(&mut self) -> Option<&mut F>

Returns the mutable current frame, if any.

pub fn visit_frames(&self, visit: impl FnMut(&F))

Visits frames in deterministic caller-to-current order.
